DUMPING-WAGON.

Specification of Letters Patent.

Patented Feb. 13, 1912.

Application filed May 18, 1910. Serial No. 561,959.

T 0 all whom it may concern:

Be it known that I, CHARLES LYNCH, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Dumping-WVagons, of which the following is a specification.

This invention relates to wagons of that type wherein the wagon body is pivotally mounted in open hearings on the frame and is also provided with means for attaching hoisting or hoisting and dumping cables, so that the load can be discharged to either side of the wagon by simply tilting the body on its trunnions, or can be raised, as by an overhead crane, and swung above the point of discharge, and there dumped.

The purpose of the invention is to provide a simplified and improved wagon of this character capable of being manipulated in a variety of ways to effect the discharge of the load; and in the accompanying drawings I have illustrated one practical form in which the invention may be embodied, in which .Figure l is a side elevation of my improved dumping wagon. Fig. 2 is a top plan view of the same. Fig. 3 is a rear end elevation of the same. Fig. 4 is a view similar to Fig. 3, but showing the body or box of the wagon turned on its trunnions so as to discharge its load at one side. Fig. 5 is a vertical section of the rear end of the wagon on an enlarged scale, on the line 5-5 of Fig. 3; and Figs. 6 and 7 are sectional details illustrating the locking bolts for one of the movable sides and the attaching means for the dumping chains.

The chief novel features of the present invention relate to the construction of the wagon box or body;'but as the same is designed for use upon and in connection with a wagon frame on which said box or bodyis so mounted as to be capable of dumping to either side, or of being raised and transported to a remote dumping position, I will briefly set forth the principal features of the wagon frame itself.

Referring to the drawings, the wagon includes the usual forward and rear wheels 10 and 11, respectively, and a reach-bar 12 connecting the front and back portions of the Above the rear axle 13 is a built-up bolster herein shown as composed of a series of superposed planks 15 secured to each other and to the axle 13 by upright angle bars 16 bolted to and across the several parts. On the inner side of the bolster thus formed is attached by bolts 17 a vertical plate 18 (Fig. 5) notched at its top at 19 to receive the rear trunnion of the box or body hereinafter described. The front bolster 14 is similarly builtup or raised but the angles which correspond to the angles 16 do not extend below the lower edge of the bolster, and to the inner side of said bolster is attached a notched plate 20 similar to the plate 18; the forward trunnion of the box being adapted to fit therein.

The box or load conveying receptacle is a rectangular structure open on top and comprising a bottom wall 21, front and rear end walls 22 and 23 rigid therewith, and a pair of movable side walls 24 and 25. The side walls 24 and 25 are provided at their ends with inwardly extending arms 26 and 27, respectively, which are strongly secured thereto as by means of bent base-plates 26 and 27 riveted to the outer sides of said walls; the inner ends of said arms 26 and 27 at each end of the wagon body overlapping each other and being hinged on a common bolt 28 that passes throughthe end wall 22 or 23 centrally of and near the top of the latter. The lower edges of the side walls 24 and 25 rest, when closed, upon the longitudinal edges of the bottom wall 21, the latter projecting preferably slightly beyond the lower edges of the side walls, as shown in the detail Figs. 6 and 7 To prevent bulging of the side walls under load, the latter are equipped with looking bolts such as 29 (Fig. 6) mounted in keepers 30 on the outer sides of the side walls 24 and 25, the lower ends of said bolts being normally urged by springs 31 into engagement with apertures 32 formed through the longitudinal edge portions of the bottom wall 21. Said looking bolts 29 are formed at their upper ends with eyes 33 for the attachment thereto of dumping chain sections 34. The longitudinal margins of the bottom plate 21 are also equipped with staples 35 (Fig. 7) or the like, for the attachment of other dumping chain sections 36 on the opposite side of thewagon body; the two dumping chain sections 34 and 36 being connected to a single central common dumping chain or cable 37. On the pivot bolts 28 by which the side walls 24 and 25 are hinged to the end walls of the box are a pair of clevises 38 to which are attached hoisting chains 39.

At the forward part of the wagon is the usual seat 40 mounted on the support 41 and a foot-rest 42, as shown in Figs. 1 and 2. On each side of the wagon is a bell-crank lever 43 pivoted at its elbow at 44 to the built-up front support of the frame, each lever having a catch 45 adapted to engage beneath the bottom of the wagon body and having at its forward end a plate portion 46, which affords means of actuating the lever by the drivers foot. Secured to each side of the support 41 is a ratchet-bar 47 with which a projection 46 on each lever is adapted to cooperate to hold the catches in a position to support the box and prevent its turning on its trunnions. The trunnions comprise stubshafts, such as 48, projecting from the end walls of the body and lying in notched bearings, such as 19, formed in the upper edges of the upstanding bolster-plates 18 and 20. The stub-shaft 48 of the rear trunnion is rigid with and projects centrally from a gear 51 (Fig. 5) secured to the rear end wall 23 of the box as by bolts 52; and the trunnion-shaft is suitably confined against endwise movement when engaged with the notch 19 by spaced collars 49 and 50 thereon.

Any suitable or approved form or style of gearing may be employed for effecting the turning movements of the body on its trunnions to effect the lateral discharge of the load; but I have herein shown one practical form of such gearing cotiperating with the gear 51 which may conveniently be employed without interfering with the detachable character of the body whereby it is enabled to be discharged at a distance from the wagon frame.

Bolted to the inner surface of the rear bolster is a bracket 52 (Fig. 5) in which is rotatably mounted a shaft 53, which extends rearwardly through an opening in the bolster. On the forward end of this shaft is a pinion 54 meshing with the gear 51, while on its rear end is secured a spur-gear 55 with which coijperates a pinion 56 rotatably mounted below the shaft 53. The shaft or axle of the pinion 56 is provided with a protruding squared portion 57 forming a wrench hold for the application of a crankarm or like tool to operate the gears and turn the box or load receptacle upon its trunnions. I

My improved wagon is capable of operation in a variety of ways. Where the wagon itself may be driven to the place of discharge of the load, the hoisting and dumping chains are not employed; but the load is discharged either by rotating the body to one side or the other through the gear, as shown in Fig. 5, or where the load is to be withdrawn from either or both sides, rather than dumped, either or both of the side walls 24 and 25 may be swung upwardly on their common hinge bolts 28, thus opening the receptacle at its side or sides. Where, however, the

wagon is employed in connection with a hoisting crane or the like to deliver the load at a point not conveniently accessible to the wagon, the hoisting and dumping chains are applied and connected as shown, the dumping chains on one side being connected to the eyes 33 of the locking bolts 29 and on the other side to the staples 35 in the edge of the bottom wall 21. The wagon body and its contents are raised by the hoisting cables 39 and swung above the point of delivery. The weight is then transferred to the dumping cables; and the first action is to withdraw the locking bolts 29 out of the holes 32 in the bottom 21. This allows that edge of the bottom to fall, the side wall 24 swinging upwardly, and the bottom wall 21 assuming a sufliciently inclined position to effect the gravity discharge of the load. The locking bolts and staples being preferably applied on both sides, the sections 34 and 36 of the hoisting chains may be so attached as to cause the box to open and dump on either side. As the weight is restored to the hoisting chains 39, the box resumes its normal position and may be swung back and lowered into place on the wagon frame; the locking bolts 29 automatically assuming the locking position under the influence of their springs 31, as soon as the weight is off the dumping chains.

From the foregoing it will be apparent that my invention provides a dumping wagon readily adaptable to use in a variety of ways and under several different conditions of service.

It will be evident that the details of structure may be modified and varied to some extent without departing from the inventive principle involved or sacrificing the advantages inherent in the device. Hence I do not limit the invention to the details shown and described except to the extent clearly indicated in specific claims.
